The tiny planet Mercury was seen traveling across the Sun in a beautiful entrance. Mercury is known as the smallest planet in the solar system (if only you agree that Pluto is not considered a planet) and is only a little bigger than the moon of the Earth.

It is also the nearest planet to the Sun, which means that it rotates much quicker than all the other worlds in the solar system.

The planet Mercury completes the rotation around the Sun for every 88 days and passes around the Earth and Sun for every 116 days. As the Mercury's orbit around the Sun is inclined compared with the Earth's orbit around the Sun, the smallest planet Mercury usually appears to pass either below or above the nearest star.

Rotation of Mercury

Now here is the time you get to see this mini-planet as it makes an entrance in front of the Sun, which happens only 13 times in a century.

But please be aware: Mercury is too small to look with the naked eye that you need to use whether a telescope or binoculars that are high powered. With just looking straight to the Sun, even if you are wearing sunglasses, it may possibly cause eye damage permanently.

NASA also wrote: "It's a rare event you don't want to miss!"

Transits in astronomy

In astronomy, transits are essential because this helps astronomers to detect planets that rotate on the alien stars.

On the other hand, here in the world of human beings, we are given a chance to foresee the art of the universe and maybe, be aware of the extreme unimportance of the Earth's concerns.

They will also allow the careless to mess up with their eyesight, so extreme caution is properly advised.

Also, you will need high-end binoculars and telescope that are perfectly fit for sun filters.

The best way to witness this transit is by watching it through live stream, just the like one that was hosted by the Royal Observatory in Greenwich, which also stated that:

"Mercury and Venus are the only planets that can be seen transiting the Sun from the Earth, as they are the only planets that orbit within Earth's orbit."

NASA has also advised about taking a look at the planet Mercury's transit.

It wrote: "With the proper safety equipment, viewers nearly everywhere on Earth will be able to see a tiny dark spot moving slowly across the disk of the Sun."

"Because Mercury is so small from our perspective on Earth, you'll need binoculars or a telescope with a Sun filter to see it. You might also be able to attend a viewing party at a local museum or astronomy club event."

"Looking at the Sun directly or through a telescope without proper protection can lead to serious and permanent vision damage. Do not look directly at the Sun without a solar filter."

The planet Mercury's transit took place on Nov. 11, 12:35 pm GMT, when the outline of the planet appeared to touch the Sun's edge.

It also reached its center around 3:19 pm before finishing its traveling time at 6:04 pm.
